Abstract (en)

The invention relates to an electronic dobby device (100) for controlling the motions of at least one weaving frame of a weaving machine, wherein the at least one weaving frame is connected to two rotors (1,2) by means of a rod and lever system, wherein each rotor (1,2) is mounted on a rotor shaft (5,6) by means of an eccentric bearing, and wherein each rotor (1,2) is individually selected to be connected or not to the rotor shaft (5,6) by means of one or several selection elements in accordance with the weaving pattern to be woven, in order to move between two possible positions that can be taken up by the rotor (1,2) with respect to the rotor shaft when the rotor (1,2) is disconnected from the rotor shaft (5,6) by the selection elements, wherein the said two rotors (1,2) each are eccentrically journalled on a different rotor shaft (5,6) and both rotor shafts (5,6) are rotating continuously and for rotating over a complete rotation require the same period of time, and in that the said weaving frame can take up at least three different positions during each machine cycle to weave the required weaving pattern. On the other hand, the invention relates to a weaving machine provided with such a dobby device (100).
